One of the numbers must be less that 1
If you mean the product, that's by definition. A composite number has smaller factors. If you multiply two positive integers, none of which is 1, together, then it follows that the product has smaller factors - namely, the numbers you multiplied together.
By finding out whether they have any factors in common. If the only factor they have in common is 1, the LCM will be their product. If they have more factors in common, their LCM will be less than their product.
Factors are smaller numbers which are multiplied to make a larger number: eg 2 and 3 are factors of 6...
No. 36 divided by 4 = 9
It's because decimals are really fractions and all numbers get smaller when you multiply them by fractions.
That's asking for the prime factorization. Writing 60 as a product of its prime factors would be 2 x 2 x 3 x 5 = 60.
Generally yes, but not in all cases. The largest prime number has over 22 million digits but only two factors whereas 60 has six times as many factors.
That is not necessarily the case.2.5*4.3 = 10.75 which is larger than either of the numbers being multiplied.
A composite number is one that can be split up into smaller factors. It can be considered to be the product of two or more prime numbers.
Any number multiplied by a fraction yields a smaller product.
You bet. As long as at least one of the factors is a proper fraction. 1/2 x 6 = 3 (product is smaller than one factor) 1/3 x 1/4 = 1/12 (product is smaller than both factors)
The product of two rational numbers, X and Y, is smaller than either of them if both are between 0 and 1.
